[SUGGESTION] Return chests

Do you think that this is a good idea?

While I was looking for shops on different servers, I noticed that someone had decided to set up a chest that said," Buy this dirt for option one, buy this dirt for option two." They were one rupee each, and were part of a poll. I think that it would be cool to be able to set up certain shops, like polls, where a player can buy an item then be refunded for the price. Just putting out an idea.
